兰州市红古区草原植被监测研究

Study on Grassland Vegetation Monitoring in Honggu District of Lanzhou

为较为全面了解红古区草原植被生长状况,为红古区草原监测、管理和保护提供数据支持,基于第三次全国国土调查划定的草原范围,采用地面样方调查方法开展了2021年度红古区草原监测工作,调查了草地产草量、盖度、高度和优势种等指标。结果表明,红古区草原产草量鲜重均值为209.44 g/m^(2),平均植被盖度为48.32%,植被高度均值为12.74 cm。优势种以红砂、针茅和珍珠猪毛菜为主。调查结果表明,近年来红古区生态治理工程的实施有效地促进了该区草原生态的良性循环。

To comprehensively understand the growth status of grassland vegetation and to provide data support for grassland monitoring,management and protection,based on the grassland area demarcated by the third National Land Survey,grassland monitoring work in 2021 was carried out in Honggu District through the sampling method of ground quadrat,aboveground biomass,coverage,height,dominant species etc.were determined.Results showed the average fresh weight of aboveground biomass in Honggu District was 209.44 g/m^(2),the average vegetation coverage was 48.32%,mean vegetation height was 12.74 cm,and the dominant species were Reaumuria songarica(Pall.)Maxim.,Stipa capillata Linn.and Salsola passerina Bunge.It indicated that grassland ecology in this area was effectively promoted by the implementation of ecological restoration project in Honggu District in recent years.
